Products Description
ABB PFEA112-65 3BSE050091R65 Tension Measurement Electronic Unit in stock
ABB PFEA112-65 (3BSE050091R65) is ABB IP65 tension electronics unit for Pressductor load cells. It supports 2 load cell inputs, inherits all measurement functions of PFEA111, and adds Profibus-DP fieldbus communication for digital tension data transmission to PLC and DCS systems.
This unit has local digital display and parameter keys for calibration and setup. It provides 4-20mA / 0-±10V analog output, with built-in signal filtering and fault diagnosis. IP65 enclosure allows direct installation on production line in dusty and humid workshop environments.
